Energy efficiency solutions for buildings
Energy system savings for companies and public buildings with high ceilings
The energy efficiency in buildings is measured adding during a year the total consumption in normal conditions of ventilation, heating, water, lighting… Savings of energy for companies, besides making them more environmentally-friendly, also favours their growth.
In climate industrial warehouses or buildings with high ceilings, energy savings is produced both in the air conditioning and heating by modifying the preset temperature. Each higher degree in summer or lower degree in winter generates 8% energy savings.
During winter, air temperature increases from 0.5 to 1ºC per meter of height, causing generated heat wastage.
During summer, the internal temperature increases in most buildings and, along with the stagnant air, generates thermal discomfort.
Magnovent, using HVLS fans, achieves certified energy savings of:
– 45% in winter / University of Liverpool
– 30% in summer / H.T.Lyons
– 30% annually / Aeropuerto de Valencia (Valencia’s airport)
Furthermore, Magnovent’s gas radiant heating systems heat only the required areas, saving up to 60% energy, and solar heating systems use the free energy of the sun to improve comfort and reduce heating costs.
ENERGY EFFICIENCY IN WINTER
NO EFFICIENT SYSTEM
The main problem that appears while climating industrial warehouses or buildings with high ceilings is that the hot air is located in the upper coats.
Additionally, heating does not attend the desired effect and heat escapes through the opened doors.
The HVLS fans homogenize the building temperature and the radiant heating heats instantly the desired areas. Energy is fully harnessed.
ENERGY EFFICIENCY IN SUMMER
NO EFFICIENT SYSTEM
The main problem that appears while climating industrial warehouses or buildings with high ceilings is that the air-conditioning does not attend the desired effect even if it is set at maximum power and cold escapes through the opened doors.
As the HVLS fans create a breeze effect in the building occupants, the preset temperature of the air-conditioning system can be increased, reducing its consumption. Adding our ceramic paint, 95% of the UV rays are reflected and the ceilings overheating is avoided.
As the effective temperature diagram of HSE (Health and Safety Executive), we obtain the following examples:
– In dry environments, taking an internal temperature of 27ºC and an air movement of 2.5m/s, the thermal sensation is equal to 21ºC.
– In humid environments, taking an internal temperature of 28ºC and an air movement of 1m/s, the thermal sensation is equal to 21ºC.
In conclusion, the air movement allows readjusting the cooling systems and, consequently, save energy in summer.
